Very good job from technical committee ;). Dual gain amplifier first shown by Kawahito's group at ISSCC 2003. 13 years ago!! Now shows up again as main "novelty" from the work of Canon.Submission rules of ISSCC say novelty is needed, not only nice results. N.O.V.E.L.T.Y.!

First of all this : I am no longer involved in any ISSCC paper selection or so, don't shoot at the piano player. Secondly : 250 Mpixel (1.5 um, 0.13 um) forced into an APS-size device is an achievement as well. Dual gain amplifier is not new indeed, but 4T pixels neither ... and so many other techniques/architectures/methods.
